Each year, several outbreaks of foodborne diseases are reported in Parana state, Brazil. Bacteria are responsible for 70% of these outbreaks and 95% of cases of food poisoning. There are reports that kitchen equipment and utensils contaminated have participated of approximately 16% of outbreaks. The aim of this study was to evaluate the microbiological quality of water, fresh foods, frozen foods, ready to eat food and sanitary conditions of three restaurants in Ilha do Mel - Paraná, Brazil, using PetrifilmTM. The results showed that 72.2% surfaces of had unsatisfactory sanitary conditions. Cutting boards, scrub sponge, kitchen sinks and dish towels had the highest average contamination. According to Brazilian law, samples of food outside of the standard were: seafood sauce, with 7,0 x 102 CFU/g of E. Coli, frozen mussels, with 7,0 x 102 CFU/g of E. coli; sample lettuce and grated carrot, considered clean, with 1,0 x 103 e 2,0 x 105 CFU/g of EC, respectively. All samples of food, in general, had high bacterial counts. Vegetables were the main responsible for the contamination of kitchen boards and sinks. The water used in the three restaurants had satisfactory microbiological quality. Better hygienic sanitary conditions were found in the restaurant where the employees had training in good manufacturing practices. | Vários surtos de Doenças Transmitidas por Alimentos são notificadas por ano no estado do Paraná, sendo as bactérias responsáveis por 70% destes surtos e 95% dos casos de toxinfecções alimentares. Existem relatos de que utensílios e equipamentos contaminados participam de, aproximadamente, 16% dos surtos. O objetivo deste trabalho foi avaliar a qualidade microbiológica da água, dos alimentos in natura, congelados e expostos ao consumo e as condições higiênico-sanitárias de três restaurantes da Ilha do Mel/PR. Para produtos de origem animal, foi determinada a contagem de aeróbios mesófilos, coliformes totais, E. coli e S. aureus. Para equipamentos e utensílios inclui-se, ainda, a contagem de bolores e leveduras. Das superfícies analisadas, 72,2% apresentaram condições higiênico-sanitárias insatisfatórias. Tábuas plásticas de corte, buchas de louça, pias e os panos de prato e de pia apresentaram as maiores médias de contaminação. De acordo com a legislação brasileira, os alimentos encontrados em desacordo com os padrões estabelecidos foram: o mexilhão congelado, com contagens de E. coli de 7,0 x 102 UFC/g; o molho de camarão, com 1,4 x 104 UFC/g; as amostras de alface e cenoura ralada, consideradas limpas, com 1,0 x 103 e 2,0 x 105 UFC/g de EC, respectivamente. Os alimentos, de um modo geral, apresentaram altas contagens bacterianas. As verduras e os legumes foram os principais responsáveis pela contaminação de tábuas e pias. A água utilizada nos três restaurantes apresentou qualidade microbiológica satisfatória. O estabelecimento que apresentou melhores condições higiênico-sanitárias foi o estabelecimento onde os manipuladores foram treinados com cursos de boas práticas de manipulação.

Food composition of Abramis brama was studied in the shallow, meso-eutrophic Hamry reservoir (Czech Republic). Fish were sampled during the daytime in the pre-spawning period (April), the post-spawning (June), summer (July) and autumn (October) in 2011. The bream sampled comprised two main size groups: small (124-186 mm) and large (210-315 mm) standard length. Twenty specimens of each size group (except April - 40 large fish) were taken for analysis on each sampling occasion. Food composition was evaluated using gravimetric methods. Over the whole season, detritus and aquatic vegetation were the dominant dietary items taken. During summer, the diet of large bream comprised mainly aquatic vegetation. Benthic macroinvertebrates and zooplankton formed a minor part of bream diet over the whole season. Specific food habits of bream could be explained by specific conditions within the reservoir and available food resources.

Fat hydrolysis in a food model system: effect of water activity and glass transition Full text

Adawiyah, D.R. | Soekarto, T.S. | Hariyadi, P.
The objective of this research was to study the effect of water activity and glass transition temperature on the fat hydrolysis in a food model system. The model system was prepared with tapioca starch, casein, palm oil and sugar as 58, 14, 16 and 12 g/100 g model matrix, respectively. Hydrolysis reaction was accelerated bycommercial lipase at six levels of water content and water activity. Moisture sorption isotherm was obtained using isopiestic method while monolayer value was determined by BET equations. Glass transition temperature was determined from amorphous ingredients of starch and casein. Hydrolysis reaction showed a significantincrease above the monolayer value at 3.55 g water/100 g solid and aw 0.19. Hydrolysis occurred even at the glassy state of the model system. The role of water in the hydrolysis reaction is more related to the water activity concept rather than glass transition concept.
